Fate cards/injuries question!

My archer suffered an injury and now has Pariah passive.
Is there any way to heal him? Or the only way was to use fate card at the end of a match?

At this point, fate cards are the only option, but nothing is set in stone

So shouldn't we be able to use fate cards at any point of the game and not only at the end of the match?
For example I didn't know what does the pariah passive mean, and it turned out to be pretty mean.

Right now I have 4 fate cards and they are just laying useless while I am playing handicapped ;/

Doesn't it feel more normal to be able to use your own content whenever you please, not only at one specific moment when you are given less information than it is necessary to decide?
